The container comprises two essentially rigid walls which are mutually connected with flexible wall. Flexible wall is made capable to move two rigid walls towards each other so that distance between rigid walls is changing. The keg additionally contains tap for pouring drink from container. Sylphon elasticity together with its shape provides mutual drawing force on two rigid walls so that two rigid walls are drawn together by force of sylphon and so that such force causes pressure in container when it is filled to displace a drink.
